This Danish School Has Installed The World’s Largest Solar Facade

A new building in Copenhagen is covered by 12,000 colourful solar tiles, making it one of the largest building-integrated solar power plants in Denmark.

The tiles completely cover the building and will provide it with 300 MWh of electricity per year, meeting over half of the new campus of Copenhagen International School’s energy needs. But aside from being the largest installation of its kind in the world according to the developers, the tiles are also architectural features in their own right. Based on a new technology developed in Switzerland, the tiles are a distinctive “sea green” – not unlike Copenhagen’s iconic Little Mermaid statue.

Special Filters

It took the researchers 12 years to figure out how they could define the colour of their solar tiles without adding any pigments to the materials. By ensuring that only certain wavelengths are reflected, they can now make the tiles appear in colours such as brick red, royal blue, golden yellow or sea green as used in Copenhagen.

Adaptive Facade

The system can be installed on existing buildings to generate electricity while allowing daylight to pass through into the building. The panels can be shifted to provide shading when needed.

A Building’s Second Skin

Delft University of Technology in the Netherlands is testing out a new innovation that acts like a building’s second skin. Existing buildings can be upgraded with the pre-fabricated material and the occupants can continue to use the space during construction.

Researchers in Gothenburg, Sweden, are also working on lighter, thinner and more durable materials that will meet stricter building regulations. One of the projects at Chalmers University of Technology focuses on ultra-thin concrete wall panels.
